The shidduch process in our community works something like this: shadchan suggests girl, boy's side looks into her, Boys side agrees, girls side looks in and agrees, they date, get engaged and married. Asking around the problem in the chain is that girls arent getting enough dates. (Generally, admitedly I dont have real data to back up this anecdotal evidence but hey neither do the :age gap" proponents).
Now going back to the numbers pushed by the "age gap" people assuming a 4% growth rate, that means 112.5 23 year olds are trying to marry 100 20 year old girls. The average guy dates 3 girls (some less some mouch more) that means 112.5 guys go on 337.5 dates. That is more than enough dates for all 100 girls. Yet the gilrs who arent getting married arent getting dates either. This cant be explained by the "age gap" at all
Each day, a bakery produces the amount of bread that it expects people will buy that day.
Throughout the day, people come in, one at a time, to buy a loaf of bread. Each person sees an entire shelf full of bread. They think, "Bread crisis! Bal tashchis! There is so much bread and no one to eat it!"
However, the baker only produces as much bread as he knows will be sold. The only reason it looks like there is more, is that all the bread is produced and displayed at one point in time. Only occasionally do one or two people ever see the empty shelves, or there is a loaf left over.
This is the source of the shidduch crisis panic. The girls all think they are ready to get married when they finish seminary, but the boys enter the shidduch system one at a time, after yeshiva or college or whenever. Over time, nearly all girls will get taken, but if you take a snapshot at one particular moment, it looks like there are way more girls than boys.
Say a hundred people walk into a bakery, each to buy a loaf of bread, but find only ninety loaves on the shelf. Will they panic?
Well, that depends. If the baker is still there, has ample supplies, and will profit enough to make it worth his while to bake an additional ten loaves (and the customers know this) then they will not panic.
If they have seen in the past that he won't bake any more than his allotment, or don't know, they might panic.
Obviously, the people panicking are not confident that His plan is to have a shidduch for everyone.
besides for all this, NASI recently published a letter stating that in actuality they have no real statistics no hard facts and its all base on what seems evident and some random headcounts in BMG. so if you anyone wants to believe this than go ahead but I feel bad for you. but I know if this Is what I believed I might kill myself. the only way I can get through this parsha is by knowing that hashem just wants me to daven right now and in the right time, the right guy will come along and I will iyh get married no matter what the age gap is.
